How to read XP

Each score is for this protocol and that specific goal, not a general rating.

XP combines how reliable the research is with how much difference it usually makes. Higher means stronger evidence for that protocol and that goal.

How to do it

Once a day at a set time, and whenever you feel tense.

1
Sit or lie comfortably
One hand on your belly helps you breathe low.
2
Breathe in through your nose for about 4 seconds
Let your belly rise.
3
Breathe out for about 6 seconds
Through the nose or pursed lips. That makes roughly six breaths a minute.
4
Continue for 5–15 minutes
The blood pressure trials used at least 5 minutes, three or more days a week, for four weeks or more.
5
Use a pacer if it helps
A breathing app or a simple timer keeps the rhythm.

The good-enough version

Five minutes of 4-in, 6-out breathing once a day.

Common mistakes

Forcing big breaths until you feel dizzy
Breathing fast instead of slow
Doing it once and expecting a lasting change
Practising while driving
